cg47船级咨询号00-94 Subj: DDG51, CG47, DD963, DDG993, FFG7 CLASS ADVISORY, MK 32鱼雷管REF: A. USS BARRY (DDG52) ACCEPTANCE TRAIL CARD 1G0125AS01/930222 B. NAVSEAINST 8515.1C鱼雷MK 46射击报告系统1。参考文献(a)报告MK 32 MOD 15水面舰艇鱼雷管(SVTT)后膛装置气压不足，导致枪管未就绪指示，抑制了舷侧鱼雷的发射。调查显示，这个问题是鱼雷MK 50能力所需的一个新的操作压力开关的结果。2.SVTT MK 32 MOD 15 (DDG 51级)基线采用鱼雷MK 50能力。所有其他被指定为鱼雷MK 50能力的舰艇已经或将接受ORDALT 15713。ORDALT 15713用一个新的压力开关(1300-1450 PSI)取代了目前的SVTT MK 32操作压力开关(1200-1350 PSI)，因为发射较重的鱼雷MK 50所需的更高的最低压力。3.要求TYCOMs建议在安装ORDALT 15713后，将最大空气瓶压力从1500提高到1600 PSI。 This 100 PSI increase will resolve the barrel no-ready condition and provide adequate pressure to successfully launch both MK 46 and MK 50 Torpedoes. 4. To monitor exercise Torpedo MK 46 launches and ensure increased flask pressure (1600 PSI) does not cause increased incidents of broaching due to reduce water entry angle. Request firing ships provide their firing data to NAVUNSEAWARCENDIV Newport (Code 8332) in addition to distribution required by ref (b). 5. Pen and ink changes to technical manuals and OPS material is authorized to indicate an increase of flask charge pressure to 1600 PSI for both weapons. 6. This advisory will be canceled within one year. 7. NAVSEA POC is: Mr. Ron Carmichael (SEA 91W432) DSN: 332-6436. 07 FEB 94 COMNAVSEASYSCOM
